Title: Densely agglomerated mass of diamond particle
Inventor: FUKIZAWA AKIRA
IPC: C01B31/06
Filed: 1985-04-01
Abstract: PURPOSE:To obtain a uniform titled mass body consisting essentially of diamond by treating agglomerated diamond particles having film of i-carbon or diamondlike carbon formed on the surface by the gaseous phase thermal cracking of hydrocarbon. CONSTITUTION:Film of i-carbon or diamond carbon (designated as i-carbon hereunder) generated by the thermal gaseous phase cracking of hydrocarbon is formed on the surface of diamond particles. The agglomerate of the particles is treated at high temp. and high pressure within a stabilizing range of diamond. Thus, the i-carbon is transformed to diamond, and the particles are bonded to form one body forming a densely agglomerated mass. Thus, densely agglomerated mass of uniform diamond particles consisting essentially of diamond is obtd. without causing deterioration of characteristics due to presence of graphite nor metallic substance and preventing generation of coarse diamond crystal particles in the mass body.

Inventor: MATSUMOTO SHOGO
IPC: B41J11/00
Filed: 1989-03-17
Abstract: PURPOSE:To increase package density and to lower the surface pressure of a sliding face to aim at a long life by forming the sliding faces of a rotary taper shaft and a fixing taper plate or a semi-fixing taper plate, in a taper face inclined to the axial direction of a torque transmission shaft. CONSTITUTION:A fixing taper plate 2 is coaxially fixed to a torque transmission shaft 1 rotated and driven. A rotary taper ring 3 is formed slidably with the taper plate 2 at the taper portion thereof. A semi-fixing taper plate 4 presses the taper plate 2 against the transmission shaft 1 via the taper ring by predetermined pressing force which slides the taper ring 3 by preset torque and the taper plate 2 is fixed to the transmission shaft 1 thereby. Consequently, a sliding face for transmitting torque is inclined to the transmission shaft 1 and pressing force is controlled constant relative to input torque to increase output torque. If the sliding tapered face is formed in multiple stages, further, higher capacity and lower surface pressure can be attempted.

Filed: 1985-03-29
Abstract: PURPOSE:To obtain an excellent vibration removal characteristic in a region from a low frequency, by applying to a vibration removing bed a vibration in a reverse phase to a resonance frequency component and damping the resonance frequency component.

Title: Magnetic recording medium
Inventor: TSUKANE YOSHIHITO
IPC: C09D101/18
Filed: 1986-03-26
Abstract: PURPOSE:To improve an electromagnetic conversion characteristic, running durability and adhesiveness by incorporating a binder, specific carbon black and specific fatty acid or the deriv. thereof into a conductive undercoat layer. CONSTITUTION:The conductive undercoat layer contains 100pts.wt. binder, 30-60pts.wt. carbon black having 100-300m<2>/g surface area by a BET method and <=0.1mum average particle size and 1-10pts.wt. fatty acid or the deriv. thereof having >=40 deg.C m.p. Not only the uniform dispersion of a coating material is made difficult by the thickening of said compd. but also the deteriorated surface characteristic of the magnetic surface is resulted from the increased surface roughness of the conductive undercoat layer to adversely affect the electromagnetic conversion characteristic if the surface area of the carbon black is <100m<2>/g. Conversely the dispersion of the carbon black into the binder is made difficult and the adhesiveness of the conductive undercoat layer to a nonmagnetic base is debased if the surface area exceeds 300m<2>/g. The surface roughness of the conductive undercoat layer is increased and the deteriorated surface characteristic of the magnetic surface is resulted to adversely affect the electromagnetic conversion characteristic if the average particle size of the carbon black exceeds 0.1mum.

Title: Logic circuit
Inventor: FUJII MASAHIRO
IPC: H03K19/0952
Filed: 1991-03-08
Abstract: PURPOSE:To reduce the number of fanouts viewed from a pre-stage and to improve the load drive capability. CONSTITUTION:The output signal of a dual-input NOR circuit composed of enhancement FETs 11, 12 and a depletion type FET 21 is fed to the FET 13 of a buffer section. Sources of the FETs 11, 12 in the dual-input NOR are connected to a power supply via a resistor and a signal at a connecting point between the source and the resistor is fed to the FET 14 of the buffer section. Since the two signals take opposite logic state to each other, the FETs 13, 14 of the buffer section turn on/off alternately. Thus, one input signal is connected to only a single FET, then the fanouts are not increased.

Title: Delay line
Inventor: BANDAI HARUFUMI
IPC: H01P9/00
Filed: 1990-03-16
Abstract: PURPOSE:To sharply reduce the size of a delay line as compared with a conventional one by narrowing an interval between both lines through a folding point on the folding point and in its vicinity as compared with the interval on a part separated from the folding point. CONSTITUTION:A strip line 13 is constituted like a zigzag shape as a whole so as to be folded through plural folding points 16 to 19 between an input electrode 14 and an output electrode 15. The interval between the input end side line part 13a and an output end side line part 13b is relatively narrowed in the vicinity of the folding point 16 and the interval is expanded in accordance with a distance separated from the folding point 16. Even when the interval between both the line parts 13a, 13b is narrowed in the vicinity of the folding point, the deterioration of characteristics due to a leaked current can not easily be generated. Since the interval (b) between both lines 13c, 13d can be made equal to the interval (a) between both the line 13a, 13b, the shape of the delay line can sharply be reduced.
